Product Introduction


Halliburton type, all could change with Halliburton parts.Pressure Poerated tester valve (LPR-N valve) is annulus operated valve

The Pressure Operated tester valve (LPR-N valve) is a full- opening, annulus pressure-operated valve.

It measures multiple closed-in pressures in cased holes where pipe manipulation is restricted and a

full-opening string is required. The nitrogen chamber is charged at the surface to a selected pressure determined by surface temperature, bottomhole temperature, and bottomhole pressure. If the intended

test requires a permanent packer that uses a stinger mandrel or seal nipple, a variety of bypass tools

are available, depending on field application, to help ensure that the formations and downhole equipment

are protected from excessive pressure buildup.


Features and Benefits
• The ball valve operates independently of internal pressure changes, such as with acidizing or fracturing operations.


• Advanced materials and processes provide a unique metal-to-metal seat for exceptional gas-holding capabilities.


• The Pressure Poerated tester valve (LPR-N valve) has been through an extensive five-day qualification testing at 400°F and15,000 psi burst and collapse pressures.


• An open-in feature allows the operator to run the Pressure Poerated tester in the hole with the ball valve opened or closed.


• Fluids can be spotted or circulated through the PRESSURE POERATED tester (LPR-N valve)with the packer unseated.


• A double nitrogen chamber can be added to the Pressure Poerated tester for use in deep, hot, high-pressure wells to reduce the operating pressure.
